DESCRIPTION (provided by applicant): We believe that alcohol use is related to the increase in frequency and severity of IPV through a process of over-arousal resulting from the cortically and psycho physiological arousing effects of alcohol during the ascending limb of intoxication and at peak BAC compounded by the unique behavioral and affective patterns of violent couples. We hypothesize that distressed violent (DV) partners will have greater difficulty regulating emotion in response to evocative partner stimuli under the influence of alcohol compared to distressed nonviolent (DNV) partners. As such, this study will utilize electroencephalography (EEG), psychophysiology and pupillary response measures to investigate the effects of alcohol on the ability to regulate emotional arousal when viewing evocative partner stimuli in distressed violent (DV) partners compared to distressed nonviolent (DNV) partners. One partner from each DV couple will be pseudo-randomly selected and yoked to a DNV partner of the same sex and comparable relationship distress for participation in the experiment. To test the overall hypothesis that over-arousal is a mechanism through which alcohol is associated with increases in the frequency and severity of IPV, the selected partners will participate in a counter-balanced placebo session and alcohol administration session during which EEG, psychophysiology and pupillary response measurements of arousal will be collected during an emotion regulation task. The study is comprised of one Stimuli Acquisition Session and two Emotion-Regulation Sessions. During the Stimuli Acquisition Session, partner stimuli for use in the emotion-regulation task will be acquired through a video-taped discussion of a disagreement via the researcher facilitated Couple's Problem Inventory (CPI). Segments of the videos will be selected where the DV and DNV partners display Contempt, Belligerence, Criticism, and Defensiveness, Stonewalling and neutral behaviors for presentation to the partner during the emotion regulation task. The selected partners (DV, DNV) will return to the laboratory on two separate occasions for the completion of the Emotion-Regulation Sessions of the study. Participants will consume either an alcohol beverage or placebo beverage (counter-balanced alcohol and placebo conditions) and complete the emotion-regulation task during which evocative and neutral stimulus clips will be shown. The data will be analyzed using repeated measures ANOVA with a between-subjects factor. We expect that DV partners will experience significantly greater arousal than DNV partners during evocative stimuli. We also expect that DV partners will experience greater difficulty regulating emotion during evocative stimuli than DNV partners and that this effect will be compounded during alcohol administration. Findings from this study will provide firm evidence that alcohol is associated with IPV a mechanism of over-arousal. Furthermore, these are processes that are amenable to novel therapeutic intervention via methods such as biofeedback and neurofeedback to increase behavioral flexibility and reduce drinking and IPV in DV couples.

描述（由申请人提供）：我们认为，酒精使用与IPV频率和严重程度的增加有关，这是通过过度唤醒过程造成的，过度唤醒过程是由酒精在醉酒上升阶段和BAC峰值时的皮质和心理生理唤醒作用引起的，并由暴力夫妇的独特行为和情感模式复合而成。我们假设，痛苦的暴力（DV）的合作伙伴将有更大的困难，调节情绪，在酒精的影响下唤起合作伙伴的刺激相比，痛苦的非暴力（DNV）的合作伙伴。因此，本研究将利用脑电图（EEG），心理生理学和瞳孔反应的措施，调查酒精的影响，以调节情绪唤醒的能力时，观看唤起合作伙伴的刺激，在痛苦的暴力（DV）的合作伙伴相比，痛苦的非暴力（DNV）的合作伙伴。将从每对DV夫妇中伪随机选择一名伴侣，并将其与同一性别和可比关系困扰的DNV伴侣结合以参与实验。为了检验过度觉醒是酒精与IPV频率和严重程度增加相关的机制这一总体假设，选定的伴侣将参加平衡安慰剂会话和酒精给药会话，在此期间，将在情绪调节任务期间收集觉醒的EEG、心理生理学和瞳孔反应测量值。该研究包括一个刺激获取会议和两个预防调节会议。在刺激获取会议期间，用于情绪调节任务的合作伙伴刺激将通过研究人员促进的夫妻问题清单（CPI）的分歧的录像带讨论获得。将选择DV和DNV合作伙伴在情绪调节任务期间展示蔑视、好战、批评和防御、阻碍和中立行为的视频片段。选定的合作伙伴（DV、DNV）将在两个不同的场合返回实验室，以完成研究的预防-监管会议。参与者将饮用酒精饮料或安慰剂饮料（平衡酒精和安慰剂条件），并完成情绪调节任务，在此期间将显示唤起和中性刺激片段。将使用重复测量ANOVA和受试者间因素分析数据。我们预计，DV的合作伙伴将经历显着更大的唤醒比DNV的合作伙伴在唤起刺激。我们还预计，DV的合作伙伴将经历更大的困难，调节情绪在唤起刺激比DNV的合作伙伴，这种影响将在酒精管理。这项研究的结果将提供确凿的证据表明，酒精与IPV有关，IPV是一种过度觉醒的机制。此外，这些过程适合于通过生物反馈和神经反馈等方法进行新的治疗干预，以增加DV夫妇的行为灵活性并减少饮酒和IPV。
